我正在尝试安装 rails，但在我需要正确安装 devkit 之前。
所以我正在做正常的程序，但我不明白出了什么问题。我正在使用 ruby​​ 2 x64，并尝试使用 DevKit x32 和 x64。这是使用 devkit x64 的。这里有什么问题..？谢谢你。

注意：在我在 x32 和 x64 情况下安装“ruby dk.rb install -f”之前。

编辑：对于试图回复 ruby​​ dk.rb 等程序的人，我已经多次这样做了：

c:\DevKit>ruby dk.rb init
初始化完成！请查看并修改自动生成的 'config.yml' 文件，以确保它包含您希望通过 DevKit 增强的所有已安装 Ruby 的根目录。

c:\DevKit>ruby dk.rb review
根据运行 'ruby dk.rb init' 生成的 'config.yml' 文件中的设置以及您的任何自定义设置，DevKit 功能将在您运行时注入以下 Ruby '红宝石 dk.rb 安装'。

C:/Ruby200-x64

c:\DevKit>ruby dk.rb install -f
